This invention relates to storage racks and in particular to that type of rack adapted for the storage of heavy elongated objects.

An object'of the invention is to provide 5 a rack for such service affording a maximum capacityand requiring va minimum of occupied floorspace. y

Another object is to make the contents of the rack easily available and a further objectisto produce a rack, having the above qualifications, of light and permanent construction and reasonable cost. f In the accompanying drawings, `I have illustrated one adaptationi of my inventionV applied to the storage of gelatin hectograph duplicating rolls so thatfit maybe readily'comprehended, but it is to be understood that 1t 1s merely illustrative andthat the scope of the invention is by no means confined thereto.v In these drawings, which form a part of this application- I Figure 1 is an elevation of my invention. Figure 2 is a sectional'view taken along the plane indicated by the arrows 2 2 of' Figure 1. l

Figure 3 is a sectional view taken along the plane indicated by the arrows 3 3 of Figure 1, while A Figure4 is a section through the 4supporting hub and spindle on the plane indicated by .arrows 4 4 of Figure 3. f

' Referring to thegures, it will be seen that the rackassembly rests upon afourlegged foundation 1. These legs are T-section, Abranching from a central hub, and ter-- minate in radial bosses, thelunder sides of which are formed to the friction bearing surfaces 2. One ofthese'is adjustable to com-l pensate for Variationen floor level -as shown at 3. The central vertical spindle 14 is force fitted into the cast -hub 5. Clamped to this spindle, and resting upon the upper surface of the central bearing hub is the cam ring 6 fixed in position by a set screw. Said cam ring 6 may also be termed a cam member or a camcollar. The upper'surface 7 of this cam ring is shaped to fourrelevations and four depressions alternating each other Vin equal radial disposition. Rlding'upon this cam ring is a follower memberv, the lower surywardly to form the arms 12 12.

face of which isformed to register to the upper surface of the cam ring 6. A freely rotatable supporting collar 13^surrounds the upper sectionof the central spindle 4.

The racks proper are composed of the four vertical box members 14, which are of triangular cross-section and vformed Aof crimped sheet metal. vThese vertical triangular members are" supported and positioned by the lower radial arms 9,v fastenedto the cam follower member, the upper radial arms 12, at

tached to the upper supporting collar` 13, and

the inclined diagonal compression struts 11. These triangularmembers in turn carry the multiple roll supporting brackets 15. Each of these brackets consists of the vertical web section `16, the inclined supporting surface 17 and the back stop lug 18. "They are fas.- tened to the sides of the aforementioned triangular members byspotwelding or other suitable means. It should bef noted that the inner ends of the brackets are slightly lower than the outer.

As will be clear from inspection of the drawings, the radial arms 12-12 are made upof metal strips. The radial arms 9 9 maybe substantially identical with the radial arms`12-12 and a description of the arms 12-12 will suffice for the arms 9 9 as well. According'to therillustration embodying the present inventionl in which four radial arms 12 12 are provided, said arms are formed from four strips 12a 12a which are identical with each other. Each of said strips 12a 120a4 slightly/greater than ninety degrees, the legs of adjacent strips `12a-12a converging out- The radial arms 9 9 adjacent to the bottomfof the rack comprise the strips`9a 9a similar to thestrips 12a l2a immediately above referred to.

As noted above, each of the box members 1 4 is of triangular cross-section. According to the illustrated embodiment of the present invention, each of said box members `comprises' three sheets of metal indicated@ the Y twenty-four of such'rolls.

numerals 14a, 146 and 140. The vertical edges of said metal members 14?) and 140 may be secured to the metal member 14a by any preferred means. According to the disclosure of the present invention said metal members 145 and 140 are secured to the` metal member 14a by means of crimping. Itwillbe clear that any other preferred means may be employed for securing the members 14a, 14?) and 140 together as a unit, or, if preferred, said members may be integral'with one another. The box structure provides rigidity in the rack without involving excess weight.

vided with the iianges 14d-14d which flanges extend towardthe axis of the spindle 4 and are disposed between the outer extremities of adjacent legs of the strips 12a-12a adjacent to the top of the leg andthe strips 9ct-'9a adjacent to the bottom of the leg.

The gelatin hectograph duplicating rolls 19 are provided with the projecting spindle ends 2O which are supported by these brackets. When vplaced thereon, they will tend to gravitate towards the axis of the rack until stopped .bythe lugs 18. j

The rack illustrated is designed to carry The rack assembly is rotatable about the central spindle 4, but such movement is checked at each 90,bythe interaction of they c am ring 6 andthe follower member 8. The

slope of the cam faces andthe interactingfol-v lowers isV such thatfif the rack assembly is given a reasonable initial movement,i1t will swing into, but stop on,.the next 90C? posi# tion, as above stated. c

Theupper end of thespindle lpengages with the socket bracket 21, and supports a shelf assembly 22 with storage for stationery, ink, or similar supplies. rIhe shelf arrangement may be varied at will or a table or other attachment substituted. Y .i

I-Iaving described my invention, what I claim as new and desire to secure by Letters Patent of the United .States is:
